DISTORTION DATA

Downstream All Digital Channel Plan, 8× Orthogonal Frequency Division Multiplexing (OFDM)

Channels, 258 MHz to 1794 MHz

See the application circuit in Figure 31. VDD = 8.0 V, IDD = 375 mA, TPADDLE = 35°C, and ZS = ZL = 75 Ω, unless otherwise noted.

NOISE POWER RATIO1

NPR

10 dB tilt, 6 dB offset at 1026 MHz, total composite

power (TCP) = 67 dBmV, VDD = 8.0 V, IDD = 375 mA

10 dB tilt, 6 dB offset at 1026 MHz, TCP = 63 dBmV,

VDD = 5.0 V, IDD = 250 mA

10 dB tilt, no offset, TCP = 67 dBmV, VDD = 8.0 V,

IDD = 375 mA

10 dB tilt, no offset, TCP = 63 dBmV, VDD = 5.0 V,

IDD = 250 mA

1 The noise power ratio gives an equivalent result to the standard modulation error rate (MER) testing but with improved dynamic range using an industry-accepted method.

Downstream All Digital Channel Plan, 190×, ITU-T J.83B, Single-Channel Quadrature Amplitude

Modulation (SCQAM) 6 MHz Channels, 54 MHz to 1218 MHz

See the application circuit in Figure 31. TPADDLE = 35 °C, and ZS = ZL = 75 Ω, unless otherwise noted.
